More Information
Summary:High-quality graphite/needle grade coke is produced with reduced impurity levels and improved coefficient of thermal expansion using an integrated hydrotreatment, catalytic cracking and coking reaction sections, employing a combination of highly paraffinic hydrotreated VGO stream and aromatic CLO stream, which is thereafter processed in a delayed coking section.
